How misleading.
At first Dani seemed sympathetic but now it turns out she's an insane bitch who has to be stopped.
shareHer turn to the "dark side" has been inevitable since she was introduced, man. Just look at her. Shes been crazy as hell since the beginning.
Shes a homeless drifter with a horrible childhood and thats why she embraced Orchestra so hard, because it was the first glimpse of stability and acceptance shes had in her whole life.
Thats why she was unconditionally loyal to Skouras. He was the only person who ever (she thought, anyway) loved and accepted her. When she found out she was wrong, that conjured up feelings of her previous abandonment and she snapped - seeking revenge on Skouras by destroying who he "loves" most, Bo.
I mean, its all explained.
